I've been thinking about the state of the Empire and a possible Remnant in the ST. To be quite honest, I find the idea of Empire being "destroyed" by their loss at Endor quite silly. Let me be clear - I am not talking about any EU material here, I am talking simply common sense. It is simply highly improbable that a vast, galaxy-spanning Empire simply crashes down in flames after the Battle of Endor. Yes, the Emperor is dead, so is Vader and so are quite a bit of high ranking officers and officials. This is a damned heavy blow, of course, but not one that results in all the Imperial forces throughout the galaxy just dropping their weapons and saying "Well, **** we lost." and going about their business. The gargantuan beast that is the Galactic Empire may be fragmented, demoralized and in chaos but certainly not defeated. As Tarkin says in ANH, the regional governors have direct control of their territories. That means that there is quite a big chunk of galaxy under Imperial control and even if those sectors are not united they still have vast resources and troops at their disposal. The Imperial Fleet at Endor was not destroyed either, although it suffered heavy losses. You need not look further than our own Earth history to see that even planetary empires take quite a while to fall. When dealing with particularly large and powerful empires, there is often no simple point of fall like a single battle or war. It is a period of long decline and fragmentation and slow disassembling of the given empire until it disappears, over a period that can even span decades or a century. Now, assuming that ST takes place 30 - 40 years after ROTJ we are left with quite a bit of options to speculate what state the Empire is in. It can be severely weakened and reduced to just a few sectors. It can just as easily be a force to be taken seriously, holding a third or a fourth of the galaxy. It can be slowly on the rise again during ST. And of course, 30 - 40 years could be enough for total annihilation of the Empire, without a single fragment of it remaining - but to be honest I find that highly unlikely.
